I'm having a problem removing duplicate records from a table. It should be easy but I can't suss it.This is an example of the data in my table:
Code:
RefDateStatus
113007111/06/2015Do Not Pay
114454306/07/2015Do Not Pay
115760714/05/2015Do Not Pay
116520705/05/2015Do Not Pay
117670108/05/2015Do Not Pay
118036218/05/2015Do Not Pay
118517015/05/2015Do Not Pay
178734020/07/2015Do Not Pay
182809915/07/2015Do Not Pay
184226010/07/2015Payment Due
184226022/07/2015Payment Query
As you can see, there are 11 records here but the last two records have the same reference number. I need my query to show the first 9 records + the record from the bottom two with the latest date (22/07/2015).
Im trying to write a query that shows all the container movements. Yet when I run the query qryFullHistory I get a duplicate value for container Off Island. Ive tried adding some criteria that says that the DateRequested has to be between the ImportDate and ExportDate but that doesnt seem to work. There are duplicate entries for container Off Island in tblContainerDetails as the same container has arrived and left and then returned on another voyage. Yet there is no entry for the second voyage in the tblMEMRContainer.
A brief description of the tables is: tblMEMR Movement requests details tblMEMRContainers the containers that were moved on the movement request. There can be more than 1 container for each request. tblContainerDetails details and dates for the container when it arrived and when it left
There are other tables but these are the 3 that are used in the query.
I have a database with an import process which normalises incoming data and appends to various tables. No issues with that. I also have a function within that process which counts the number of new entries for a summary popup when the process has completed.This works by querying the staging table, prior to the append, into a recordset and using the .RecordCount to increment the count (multiple files can be imported at once so this effectively provides a running count, per file, to give a total for the whole import)
I thought it was working fine but this morning I noticed that the count which appeared on the popup was 1 greater than the number of actual new records. I checked the source files and noticed that, for whatever reason, there was a duplicate entry in there. So I presume that's why the count was out by 1.
There's no integrity issue in the main tables as the composite primary keys ensure that duplication shouldn't be a problem. Indeed, the record in question, duplicated in the source, appears only once in the main table post-import. So not too worried about that.
However, I need the count in the popup to be accurate (it tells the users how many new entries require further investugation). And what's puzzling me is that I use DISTINCT in the query, which I would have thought should eliminate any potential dupes in the recordset and thus provide the correct count. It seems it doesn't?
Code: Public lngNewBalancesTBI As Long ' Defined in a separate module... ------- Dim dbs As Database Dim rst As Recordset Dim strSQL As String
[code]....
Why the dupe, which is still present in the staging table, also makes it over to the recordset, even though I'm using DISTINCT?
Ok well I thought I was doing this right but it appears I have not. I am drawing data from two tables. Both of them related by the person's name. One table I am pulling the unique ID number, the other table contains the name. I have a PO (Purchase Order) field being pulled from the table that holds unique ID. Or lack there of, so I am pulling all the records that contain no PO number. However duplicate unique ID's are being pulled. The way my query is set up now is:
Unique ID Number Name Count (Number of Procedures) Charges PO Number - Criteria: "Is Null"
I have also right click in the table view area, in the properties I selected Unique values. I have to assume that this would have held back any Dupes from the output. However this is not the case. When I looked in the help files the only thing I could find was:
http://office.microsoft.com/en-us/a...0840151033.aspx Quote: "If you want to see only unique values in a result set, you can specify that you want to exclude duplicates from the result set.
In the Database window, click Queries under Objects, click the query you want to open, and then click Design on the database window toolbar. Right-click the background of the Diagram pane, then choose Properties from the shortcut menu. Select DISTINCT values. The Query Designer inserts the keyword DISTINCT in front of the list of display columns in the SQL statement.
Note If you use the DISTINCT keyword in Microsoft SQL Server, you cannot modify the data in datasheet view."
The problem with this is my properties box does not offer a Distinct Values option. So my question is. Is there an expression I can place in the Unique ID field that will exclude any duplicate records.
I currentlyt have a search form that searches criteria based on a textbox. After entering data a macro runs, and opens up a query with the results. After that query opens i have macro that runs a duplicate query off of the query initally opened based on the search results. What i would like to have is a macro that removes the duplicate records from the duplicate query and display the remaining records.
I have a table with at least 13.000.000 records. There are many duplicates records... For example
ID Name Family mobile car number chassis Register_Year 1 Roy Jalbout 9999 123456/G ASF4546 2005 2 Roy Jalbout 9999 854658/G GRK554JFJD 2009 3 Tony Elishah 1234 854658/G GRK554JFJD 2012 4 Sam Markos 5478 854658/G GRK554JFJD 2014 5 Roy Jalbout 9999 123456/G ASF4546 2005
As you can see ID Number 2,3,4 have the same car but every one bought from another so it's not duplicates
The duplicates here is the ID's number 1,5. So how to remove the duplicates. I remember you i have at least 13.000.000 records. I try to make a query to find duplicates then i make a copy of the original table and than i should make a primary key then append the data from the original table to the copy table, but here i have more than one criteria
When I made a query to find duplicates the result was 680.000 records and every one have a minimum 2 duplicates an maximum 4 duplicates so it's about 2.500.000 duplicates records at least....
I'm creating a job/timesheet database and have a problem...
I have a main timesheets table that includes every job/piece of work thats been done (sometimes multiples for each employee each day). Each record contains a ref to the employee, ref to the contract, ref to the type of work, time taken and date.
There are then various tables that support the main table, which provide actual employee names etc.
I want to produce a query that provides the number of hours undertaken on each day of a particular week for each employee. So I'd have one row for each employee from the employees table, then a field for the sum hours for Monday through Friday.
The way I was going about this was
- to create five query's for the main timesheets table that would limit the entries to the five days in question - Monday-Friday. That worked fine.
- to then create a query that takes the employee name and using each of the five day based queries perform a Sum Total on the time field to give me the total hours worked for each day for each employee. That also worked fine, but the trouble is it removes any null values. So, if I only include the first day there might be 80 employees listed, but when I include the second day as well that goes down to 72 - presumably as 8 employees who entered timesheets for day 1 didn't for day 2. By the time I add all five days, I have almost no employees. I assumed that there would be a query level property to set, but i can't see one.
Also, is there a simpler way to do what I want? If I can get this working I'd like to replicate to breakdown by contract, job type etc in the same way as I have with employees.
I have a table that has mutliple records for the same person. I know how to create a query to remove duplicates but i don't know how to create a table to remove duplicates but keep the most recent record. Is this possible?
ie client status date 123 A 1/1/07 123 C 2/5/06 123 A 9/3/07
In my simple database (attached), I need to mass duplicate Tasks and their Notes.
I have three tables: tbTasks (PK: Task_ID), tbNotes (PK: Note_ID), jtbTaskNotes (FKs: Task_ID and Note_ID). jtbTaskNotes is my many-to-many junction table that ties Tasks to Notes.
The main form (fmTasks), bound to tbTasks, has a subform (sbfm_TaskNotes) that displays notes associated with each Task. On themain form,you select which Tasks you want duplicated via a checkbox. The append query (quCopyTasks) will duplicate all tasks that have the checkbox checked. All good there. However, I can't figure out how to also duplicate each task's Notes.
I found Allen Browne's solution [URL] ....., but that only handles duplication of one record at a time, whereas I need to duplicate many records at a time (sometimes 10+ records). How do I go about duplicating multiple Tasks and their associated Notes?
Before you ask "why are you duplicating records?": There are times when tasks need to be re-accomplished and therefore need to have a new record. It's easier to duplicate records than it is to hand-jam everything again.
I have made a crosstab query that is sporatically making duplicate counts. I'd like to know how to fix the problem, but more importantly - I'd like to know why and how my query is giving me these results so I can avoid making this same mistake again.
The relationship is set up so that all records from one table are returned, with only matching records from the other - so no problems that way as far as I can see. This is my crosstab query that is giving some counts of the same record as being matched sometimes two, three, or even four times:
TRANSFORM Count([Testing DB].[DB_ID]) AS [CountOfDB_ID]
SELECT [Testing DB].State, [Location].[North], Count([Testing DB].[DB_ID]) AS [Total Of DB_ID]
FROM [Testing DB] LEFT JOIN [Location] ON [Testing DB].[Address] = [Location].Address
WHERE (([Testing DB].[Window Length]) Is Not Null))
GROUP BY [Testing DB].State, [Location].[Size]
ORDER BY [Testing DB].State, [Location].[Size]
PIVOT Format([Date],"mmm-yyyy");
When I do a simple query for a list of the records being counted by this query, I can see the duplicate entries and can eliminate them simply by adding "Distinct" to the select statement - but I haven't had any luck adding any kind of distinction with this crosstab that will do the same.
How can I eliminate duplicate counts of records in my crosstab? If anyone has a suggestion, it would be much appreciated.
I thought I had just about finished my DB but now Ive printed out and checked my reports I notice I have several records in different types of reports showing duplicate records. Iv'e gone back over the queries and there are one or two duplicates in several of my queries that I did not notice before because there are are only the odd one or two. No matter what I do I can't stop this happening. I think it must be something to do with the dates in my payment table. PaymentID is key field - foreign key is MemberID. One member can have several paymentID's a new one every year when membership renewed. The problem seems to be when the member has two payment dates in the same year. This shouldn't be anyway but the database has not been used properly with entry dates missing, written over of wrong dates etc. Ive tried to correct this but do not want to tamper with past payment date records. I already have 'select distinct' in my queries and have tried 'distinct row' which seems to return even more duplicate records. Im pulling my hair out over this there must be a way to return the records from members showing just 1 only of their very latest payment record/date. Im using this expression in the query.
LastPaid: (SELECT MAX(PaymentDate) FROM S_Payments_Table WHERE S_Payments_Table.MemberID =S_Members_Table.MemberID)
I have been hitting my head against the wall to have my query not show any DUPLICATE STOCK CODES in my report..I have two "AQN.PR.A" records, I only want my report to print one "AQN.PR.A"...I have three "ALA" records, I only want my report to print one "ALA"AQN.PR.A
I have a table and there are so called duplicate records (not entirely duplicate because there is field with the date of creation and other differences in a few fields, but from my point of view they are duplicates.). I d like to make a query which shows me only the newest record in case of duplicity.
ID userno ticketno Status userno ticketno Status 1 1211 YAB 1211 YAB LIVE 2 1211 YAB 1232 ACE LIVE 3 1232 ACE 1232 AAT INVALID 4 1232 ACE 5 1232 ACE 6 1232 AAT
I am trying to write an update query in MS Access that will update only the first record of any custno with the status so that my final table A looks like this:
when running the attached report I am getting duplicate records. If using the protocol specified tc02026 there should be 8 records total. When running the report it pulls from both queries which have select criteria. How do I limit the report to only give me the 8 records and eliminate the duplicates? When I run each query it only gives me the 8 records I am looking for. Each Sample# in the report is a unique number(to help see the replicates).
Why I am getting duplicate results for some of my records in a query. I have unique values set to Yes. I have also validated that the tables I am using don't have duplicate data. SQL is below.
SELECT DISTINCT [tbl_Rewards Activity Report - By Member Number].[Member Number], [tbl_Rewards Activity Report - By Member Number].[Last Four], [tbl_Rewards Activity Report - By Member Number].[BAL ID], [tbl_Rewards Activity Report - By Member Number].[Primary Name],
I have this small database, I would like to have your support to setup this query "QryResults" in order to remove the duplicate records, I can't find a way to get shown only true records, for some reason I'm getting duplicate rows and fake values, the query is calculating operations from two different queries and a table.
I have 10 tables linked in one query. 9 tables are linked to one main table (one to many relationship).I want to get rid of duplicate records that show different data in multiple columns. I want only one record of this but retain with different data under different columns to be separated by commas. For example: I want this...
Code: Employee # Name Course Start Date Completion Date 1 John Smith MS Office Training 1/1/2010 5/1/2010 1 John Smith Python Training 1/30/2011 4/1/2011 1 John Smith Leadership Development 6/27/2013 9/1/2013 1 John Smith Sensitivity Training 9/5/2010 - 2 Hank Joel MS Office Training 8/1/2010 10/1/2010 2 Hank Joel Sensitivity Training 8/1/2010 10/1/2010 2 Hank Joel WHMIS Training 11/15/2010 12/1/2010 3 Jane Doe Leadership Training 7/18/2011 9/26/2012
To turn like this:
Code: Employee # Name Course Start Date Completion Date 1 John Smith MS Office Training, Python Training, Leadership Development, Sensitivity Training 1/1/2010, 1/30/2011, 6/27/2013, 9/5/2010 5/1/2010, 4/1/2011, 9/1/2013, - 2 Hank Joel MS Office Training, Sensitivity Training, WHMIS Training 8/1/2010, 8/1/2010, 11/15/2010 10/1/2010, 10/1/2010, 12/1/2010 3 Jane Doe Leadership Training 7/18/2011 9/26/2012
I am using two tables to find the data (main - "employee tbl" and "courses tbl")I have been trying to follow Allen Browne`s method, but I`m unsuccessful. This is the code I've put in SQL of this query:
However, I am prompt with "Syntax error in query expression".It also prompts another expression to be in error when I include the above but it runs okay when I don't do the above:
Quote:
WHERE (([Employee Tbl].[Employee #]) Like [Enter Employee ID or leave blank for ALL employees] & "*")
I placed the following in VBA module:
Code: Public Function ConcatRelated(strField As String, _ strTable As String, _ Optional strWhere As String, _ Optional strOrderBy As String, _
I have a table with duplicate records (which is ok) and I want to return distinct data for each client.
It works fine when there is only two fields returned however, when I add a third field to the query it no longer returns only the Distinct records - I am getting Duplicates returned.
I.E
SELECT DISTINCT tblClient.ClientNo, tblClient.Name FROM tblClient
Works fine with only the Distinct records for each client returned
However
SELECT DISTINCT tblClient.ClientNo, tblClient.Name, tblClient.Address, tblClient.OrderValue FROM tblClient
Now returns Duplicates!
Is there a limit to the number of fields to be returned using DISTINCT or what else could be the problem? Should I be doing this some other way?
I'll first of all explain the purpose of the query. I've built a database to record the admission details of patients admitted to hospital. Amongst other things, the database captures date/time of admission and date/time of discharge.
The query I am building needs to show patients with multiple admissions, and in particular, the number of days that have elapsed since they were last discharged. Within my query is the following subquery that I had written to show this aspect of it:
(SELECT TOP 1 Dupe.[Discharge Date] FROM [Inpatient Database] AS Dupe WHERE Dupe.[CHI Number] = [Inpatient Database].[CHI Number] AND Dupe.[Discharge Date] <= [Inpatient Database].[Admission Date]) AS [Previous Discharge],
Note: "CHI Number" is a unique reference number assigned to every patient.
I then display in a column [Admission Date] - [Previous Discharge].
This works fine where a patient only has one previous admission. However, where a patient has multiple admission, the subquery always returns that patient's first discharge date instead of their most recent discharge date (because I have used the "TOP 1" predicate). It seems that it should be straightforward enough, however I can't seem to work around it. Anything I try results in errors, and so I keep defaulting back to my "TOP 1" solution.
i.e. What I want it to show is: Name.......Admission Date...Discharge Date.... Previous Discharge... Days Between Admissions Joe Bloggs ..01/01/2014 .......10/01/2014 Joe Bloggs ..15/01/2014 .......20/01/2014 .......10/01/2014 ..............5 Joe Bloggs ..27/01/2014 .......01/02/2014 ........20/01/2014 .............7
However, what it actually shows is: Name ......Admission Date ...Discharge Date ...Previous Discharge ...Days Between Admissions Joe Bloggs ..01/01/2014 ......10/01/2014 Joe Bloggs ..15/01/2014 ......20/01/2014 ........10/01/2014 .............5 Joe Bloggs ..27/01/2014 ......01/02/2014 ........10/01/2014 .............17
